Abstract

A microwave energy interactive structure includes a first susceptor film including a first layer of microwave energy interactive material supported on a first polymer film, a moisture-containing layer joined to the first layer of microwave energy interactive material, an adjoining layer joined to the moisture-containing layer such that the moisture-containing layer is disposed between the susceptor film and the adjoining layer, and a second layer of microwave energy interactive material on a side of the adjoining layer opposite the moisture-containing layer. The adjoining layer may be joined to the moisture-containing layer by a discontinuous adhesive layer.

Claims11

Dependent claims

A microwave energy interactive structure comprising:

a first supported susceptor film and a second supported susceptor film joined to one another, the first supported susceptor film and the second supported susceptor film each comprising microwave energy interactive material supported on a polymer film, the microwave energy interactive material being joined to a dimensionally stable support layer, wherein the first supported susceptor film and second supported susceptor film are joined to one another by a first layer of adhesive disposed between the support layer of the first supported susceptor film and the polymer film of the second supported susceptor film, the first layer of adhesive being discontinuous so that a plurality of unjoined areas are defined between the support layer of the first supported susceptor film and the polymer film of the second supported susceptor film;
and
a corrugated material joined to the support layer of the second supported susceptor film by a second layer of adhesive.

Dependencies are inferred from the claim text.
